New data from NASA's Juno orbiter reveals Jupiter is slightly smaller and more 'squashed' than scientists previously thought.

Jupiter shrunk not; the yardstick improved. The largest planet of the solar system has been used decades as a sort of calibration beacon: a “known” giant, whose existence largely goes unnoticed, whose ...

The planet's radius from pole to center has been revised to 66,842 km, and at the equator to 71,488 km. That makes it about 12 km smaller along the poles, and about 4 km smaller at the equator, than ...

“Textbooks will need to be updated,” study co-author Yohai Kaspi, a planetary scientist at the Weizmann Institute of Science in Israel, said in a statement. “The size of Jupiter hasn’t changed, of ...

The solar system’s most giant planet is slightly less of a giant than scientists once thought. Jupiter, a planet so huge it could hold 1,000 Earths, is 8 kilometers less wide at its equator and 24 ...

According to this early data, Jupiter’s equatorial radius was around 44,423 miles (71,492 kilometers), and its polar radius ...

New research data using NASA’s Juno spacecraft shows Jupiter is slightly smaller and flatter than decades-old estimates.

An international team of researchers using data from NASA’s Juno mission has redefined the physical dimensions of the gas ...

Jupiter may be a bit more petite than expected, and that could have a big impact on how scientists model the mysterious ...

Jupiter’s swirling storms have concealed its true makeup for centuries, but a new model is finally peeling back the clouds.

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new ...
